Patent JP-S61181959-A (JP)
Title: Signal detector for ultrasonic apparatus
Inventor: TAKASUGI KAZUO
IPC: A61B8/00
Filed: 1985-02-08
Abstract: PURPOSE:To minimize effect from the inter-electrode capacity of a piezo-electric element and the electrostatic capacity of a cable, by connecting a low-impedance element to both ends of the piezo-electric element to detect the current flowing therethrough. CONSTITUTION:A signal source impedance 100, a parallel impedance 200, a series impedance 300 and a receiving amplifier 400 whose input impedance is indicated by 401 are so arranged that an output develops at the output 402 of the amplifier corresponding to the value of the current flowing through the input impedance 401. The input impedance 401 of the amplifier shall be a load element so as to be sufficiently lower in the impedance value as compared with the equivalent signal source resistance 12 of a piezo-electric element and the series element 300. In this case, normally, it is easy to make the sum of impedance values of 401 and 300 lower than that of the parallel impedance 200. This enables efficient flowing of the signal current from an echo signal source 11 to the 401 thereby reducing the deterioration of signals due to parallel elements to a slight level.

Title: Circuit switching system
Inventor: TOKI RIYUUICHI
IPC: H04L45/24
Filed: 1984-02-10
Abstract: PURPOSE:To attain a circuit switching system which can switch a circuit instantaneously to a spare circuit corresponding part without discontinuing the communication, by transmitting the responses showing the busy states every fixed interval from a packet exchange and switching circuits while a transmission suppressing state is preserved between the packet exchange and a terminal circuit. CONSTITUTION:A CPU1 transmits an own station busy command 14 to a working circuit corresponding part 2a to start a switching action after receiving a switching indication signal 4. Then the CPU1 transmits an action mode resetting command 5 to a spare circuit corresponding part 2b to transmit a command signal 6 to a circuit 3 when the connection is secured to the circuit 3. However the command 6 does not reach the circuit 3. Here the CPU1 delivers a switching preparatory end report 11 to show that the preparatory is through with switching to the part 2b. Then the CPU1 waits for a data transmission enable report signal 8 which shows that the communication can be started between the part 2b and the circuit 3.

Title: Detecting circuit of voltage drop
Inventor: NOZAWA YUUJI
IPC: G05F1/56
Filed: 1981-02-17
Abstract: PURPOSE:To detect the voltage drop of the data bus terminal of an IC memory, by connecting the joint between a resistor connected between both input terminals and a Zener diode to the base of a transistor via a resistance and providing an output point to the collector of the transistor. CONSTITUTION:A resistor 8 having the sufficiently large resistance value compared with the emitter-collector resistance value is provided when a transistor TR7 is turned on. Thus the power supply voltage Vcc of an IC memory emerges substantially to an output terminal. When the voltage Vcc lowers, the currents flowing to a resistor 4 and a Zener diode 6 reduce. Thus the voltage at a joint between the resistor 4 and the diode 6 is constantly set at Vz. When the voltage Vcc lowers less down to a level equal to the voltage Vz, no base current flows to turn off the TR7. Therefore, the fluctuation of the voltage Vcc is detected and delivered to a terminal 3 after setting the Zener voltage at a proper level and before the voltage Vcc lowers so less that the data bus terminal of the IC memory becomes uncirtain.

Filed: 1979-02-26
Abstract: PURPOSE: To reduce the dead time of a step-up control for an electric motor vehicle by switching the step-up time in response to the voltage or current applied to a drive motor.  
     CONSTITUTION: When the first pattern VP 1  is applied from the first pattern generator 1 to a second pattern generator 10, the generator 10 generates the second pattern VP 2  having lower by the value of a subtraction pattern 8a than the first pattern VP 1  to the second comparator 11, which compares the second pattern VP 2  with a detection signal VM. When VM<VP 2  in the second comparator 11, the comparator 11 produces a second discrimination signal 11a to a logic circuit 12. Since VM<VP 1  in the first comparator 3 to produce first discrimination signal 8a to the logic circuit 12, the logic circuit 12 produces the first logic signal 12a to the second delay timer 13, which thereupon produces a step-up pulse 14a having a pulse duration caused by the delay time T 2  thereof. When the detection signal VM becomes high to become  VM>VP 2 , the logic circuit 12 similarly produces the second logic signal 12b to the  first delay timer 4, which thereupon produces a step-up pulse 14a having a pulse  duration caused by the delay time T 1  thereof.

Abstract: PURPOSE:To generate an input current pulse with a long time width which a photocoupler can sense by inserting a stretch resistance in the middle of a route where the driving power source of the photocoupler charges a capacitor. CONSTITUTION:The capacitor 41 of a pulse stretch circuit 4 is charged up to a voltage+V1 in a state that a switch 1 is turned off by the driving power source of a light-emitting part in the photocoupler 2.
